Fast forward almost a # decade, and latent bugs in the code converting this hack from freeze # flags to freeze locks combine with lockdep bugs to make this reproduce # frequently enough to notice page faults racing with freeze. # # Since the hack is unnecessary and causes thread race errors, just get # rid of it completely. Making this kind of vfs change midway through a # cycle makes me nervous, but a large enough number of the usual # VFS/ext4/XFS/btrfs suspects have said this looks good and solves a # real problem vector. # # And once that removal is done, __sb_start_write is now simple enough # that it becomes possible to refactor the function into smaller, # simpler static inline helpers in linux/fs.h. The cleanup is # straightforward. # # Summary: # # - Finally remove the "convert to trylock" weirdness in the fs freezer # code. It was necessary 10 years ago to deal with nested # transactions in XFS, but we've long since removed that; and now # this is causing subtle race conditions when lockdep goes offline # and sb_start_* aren't prepared to retry a trylock failure. # # - Minor cleanups of the sb_start_* fs freeze helpers" # # * tag 'vfs-5.10-fixes-2' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: # vfs: move __sb_{start,end}_write* to fs.h # vfs: separate __sb_start_write into blocking and non-blocking helpers # vfs: remove lockdep bogosity in __sb_start_write # < /opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 f01c30de86f1047e9bae1b1b1417b0ce8dcd15b1 # < make -s -j 120 ARCH=um O=/kisskb/build/linus_um-defconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 defconfig # make -s -j 120 ARCH=um O=/kisskb/build/linus_um-defconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 /kisskb/src/arch/um/os-Linux/signal.c: In function 'sig_handler_common': /kisskb/src/arch/um/os-Linux/signal.c:51:1: warning: the frame size of 2960 bytes is larger than 1024 bytes [-Wframe-larger-than=] } ^ /kisskb/src/arch/um/os-Linux/signal.c: In function 'timer_real_alarm_handler': /kisskb/src/arch/um/os-Linux/signal.c:95:1: warning: the frame size of 2960 bytes is larger than 1024 bytes [-Wframe-larger-than=] } ^ LINK linux Completed OK # rm -rf /kisskb/build/linus_um-defconfig_um-x86_64 # Build took: 0:00:28.675309
